This series adds frame specific min/max qp controls for hevc and layer
wise bitrate control for h264.
Chnages since v2:
- addressed comments.
- added driver side implementation for new controls.
Dikshita Agarwal (3):
media: v4l2-ctrl: Add frame-specific min/max qp controls for hevc
media: v4l2-ctrl: Add layer wise bitrate controls for h264
venus: venc: Add support for frame-specific min/max qp controls
